IMPROVEMENT IN LOCKS FOR MEETING- RAILS OF SASHES.

, Specification forming part of Letters Patent No. 115,341, dated May30, 1871.

I, WILLIAM MILLER, of Boston, in the county of Suffolk and StateofMassachusetts,

have invented certain Improvements in Sash- Locks, of which thefollowing is a specification:

Figure 1, perspective view. Fig. 2, sectional elevation.

The object of this invention is to produce a window-sash lock which willnot only efi'e'ct the object indicated. inits title, but will also bindthe sashes tightly together when locked,

and prevent the same from rattling, and it consistsof a pivoted bar onthe outer sash, which engages with a slotted ear on theinner sash, andis bound by a pivotedlever on the latter sash, in such manner as to drawboth sashes tightly together, as will hereinafter more fully appear.

In the drawing, A represents a bar or lever pivoted to lugs B of plateC, which latter is attached to the upper sash D. The bar A is providedatits outer end with alug, E, which projects from the same, leaving aslot, 6, between itself and bar A. F represents a spring located in acasing, G, which forms apartof plate 0. Said spring bears against thelower endof bar F, which end has beveled corners,-

as shown, and holds the bar in an elevated or depressed position, asshown. G represents a plate located on the lower sash H, which plate isprovided with vertical lugs or cars I, be-

I I tween which is a vertical slot, J. K represents a lever pivoted tothe back part of plate G,

which lever is provided with a curvedhandle, L, and swings freely oversaid plate behind lugs 'I,its motion being circumscribed by a pin underthe under side thereof, which engages with the projection of plate G onwhich said lever is pivoted.

Operation. When the parts are not locked the bar A is in a verticalposition, as shown in Fig. 1, being held in this position. by the springwhich bears against the back of said bar. To look the sashes the bar Aisbrought down into the po sition shown in Fig. 2, when its outer endrests in the slot J, between lugs I I. The lever K is then swung aroundinto the slot 0 in the end of bar A, and the curved edge of. handle L,bearing against the head of said slot, draws the bar -A with the sash Dinward, thereby closely binding both sashes together, as shown in Fig.2.

Having thus fully described my invention, what Iclaim as new, and desireto secure by Letters Patent, is-- v 1. The pivoted lever A, providedwith slot 0, and held in position by spring F, substantially asdescribed.

2. The plate Gr, provided with lugs II and slot J, and pivoted lever K,said lever having curved handle L, substantially as described.

3. The pivoted lever A, in combination with the pivoted lever K and lugsII, as and for the purposes set forth. a

In testimony whereof I have signed myname to this specification in thepresence of two sub scribing witnesses.

WILLIAM MILLER. Witnesses:
